Detailed Description
As described in the background art, a real-time alarm mechanism is needed, which can directly alarm in real time for the situation that the belt extraction material box is still lowered in the locked state of the trolley equipment.
Specifically, a carrier is fixed on the loading platform, a fastening buckle is arranged on the carrier, and when the fastening buckle is in a locking state, the material box is fixed on the carrier through the fastening buckle; when the fastening buckle is in a loosening state, the material box can be extracted by the trolley equipment. The last two steps of extracting the material box by the overhead crane device are as follows: unlocking the fastening buckle by the loading platform; after the fastening buckle is unlocked, the fastening buckle loosens the material box.
When the machine works normally, the fastening buckle of the machine is in an unclamped state, the automatic control end sends an extraction instruction to the trolley equipment after receiving the safety signal sent by the machine, and the trolley equipment sends the extraction instruction to the target machine after receiving the extraction instruction, so that the material box is successfully extracted.
However, when the machine is not working normally, the fastening buckle of the machine is in a locking state, and when the equipment state is confirmed to be normal, manual operation is needed to be carried out, so that the fastening buckle of the machine is switched from the locking state to the loosening state; after receiving the safety signal sent by the machine, the automatic control end sends an extraction instruction to the trolley equipment, and after receiving the extraction instruction, the trolley equipment goes to the target machine to prepare for extracting the material box. At this time, the material box is not switched from the locking state to the releasing state due to other reasons, the lifting device still drops the belt, so that the lifting device fails to extract the material box, the machine station can alarm, and the belt and the motor of the lifting device can be possibly damaged.
At present, all the machine stations have no real-time alarm mechanism which is directly used for the trolley equipment to lock the fastening buckle of the machine stations, and the prevention effect can only be achieved by a verbal announcement mode. Once human negligence occurs, the overhead hoist equipment is damaged and cannot be remedied and recovered.
In order to solve the problems, the technical scheme of the invention provides an automatic carrying system and a working method thereof, wherein a position sensing sensor is arranged at the edge of a loading platform, when a trolley device moves to the position right above the loading platform, the position sensing sensor detects the trolley device and sends a in-place signal, a grating detector acquires the in-place signal and reads the number of signals of a shading sensor, when the number of signals of the shading sensor is 1, the loading platform sends a safety signal to an automatic control end, and the automatic control end sends an extraction signal to the trolley device to extract a material box; or after the automatic control end acquires the safety signal and the in-place signal at the same time, sending an extraction signal to the overhead crane equipment for extracting the material box. If the two conditions are not satisfied, the overhead crane moves away from the loading platform, and the extraction and the alarm of the material box are not performed. The position sensor and the grating detector play a double-confirmation role, so that the safety state of the loading and unloading platform can be early warned in advance, and the equipment loss is minimized.
